Product and Software: This article applies to the AP-12x series and requires ArubaOS 3.3 or above.


AP-12x can operate with the following Power-over-Ethernet (PoE) standard:

  • 48 V DC 802.3af or 802.3at or PoE + interoperable PoE with intelli-source PSE sourcing intelligence (both ports)
  • 5 V DC for external AC supplied power (adapter sold separately)


12x APs can run on 802.3af, 802.3at, and DC power. When running on 802.3af, insufficient power may affect the ability to run the dual-radio HW at full capacity.






Full functionality

DC, POE > 48V, or single-radio


One Ethernet port disabled

POE voltage > 45V, < 48V


Two TX chains per radio, one Ethernet port disabled

POE voltage < 45V


Power is checked using the hardware voltage sense pins when OS boots up and every minute thereafter.


When the functionality is disabled, you must reboot the AP to re-enable the functionality.


Link status determines which Ethernet port to disable. If only one port is reporting that the link is up, the other port is disabled.  If both ports are up, or both ports are down, then port 1 is always disabled and port 0 is left active.
